Answer:
the formula for a function d(x) that describes the distance is
Step-by-step explanation:
We are going to define final point , and initial point , then we can use , so we obtain , by developing it
This formula describes the distance between those two points and involves x
Answer:
6 multiple choice questions and 22 open/extended response questions
Step-by-step explanation:
Let x be the number of multiple choice questions
Let y be the number of open response questions
Thus, we have a system of equations:
2x+4y=100
x+y=28
Solve bottom equation for desired variable, then plug in to top one:
x+y=28
x=28-y
2(28-y)+4y=100
56-2y+4y=100
56+2y=100
2y=44
y=22
Plug y back into bottom equation to get x:
x+22=28
x=6
So there are 6 multiple choice questions and 22 open/extended response questions.
Answer: 1.45 is a growth factor.
Step-by-step explanation:
Exponential growth function: , where A = initial value , b = growth factor (if b>1)
Here, The expression models the number of billions of genetic sequence bases available in the public database of the Whole Genome Shotgun project t years since 2002.
Here, b=1.45 >1
Thus,1.45 is a growth factor.
You can use calculus ( related rates). Given the rate os change of the radius for example you can find the rate of change of volume using differential calculus.
Answer:
The X and Y intercepts to the equation -3x - 7y = 84 is
x-intercept (s): (−28,0)
y-intercept (s): (0,−12)
Step-by-step explanation:
To find the x-intercept(s), substitute in 0 for y and solve for x
−3x−7⋅0=84
Solve the equation.
x=−28
x-intercept(s) in point form.
x-intercept (s): (−28,0)
To find the y-intercept(s), substitute in 0 for x and solve for y .
−3⋅0−7y=84
Solve the equation.
y=−12
y-intercept(s) in point form.
y-intercept (s): (0,−12)
Hope this helps.
